Introduction MicroE Systems was founded to advance encoder technology to a level never before achieved. Our objective was to design encoder systems that would be small enough to fit into densely packed OEM equipment designs, affordable enough for cost-sensitive applications and easy enough to enable installation, setup and alignment by assemblers with little training. We are pleased to say that all of these goals have been realized with the introduction of the Mercury family of encoders.

Installation Instructions Linear Encoders 1 Attach the scale to the base slide. Reference the preferred datum on the interface drawing for either end or center index orientation. Depending on the mounting method, attach the scale to the slide with adhesive. Refer to pg. 8 for details. Be sure the grating surface of the scale faces the sensor. There is to be no contact between these surfaces or damage may result. 3 Be sure power is off before connecting the sensor.
Installation Instructions Linear Encoders 4 MAIN TRACK ALIGNMENT If benching dimensions cannot be provided, proper sensor alignment may require minor adjustments to the sensor head position with respect to the scale. This can be performed by maximizing the sine/cosine signals from the M1200 or M1500P. Using an oscilloscope in the X/Y mode, monitor the sine/cosine signals (refer to the interface drawing for pinouts) while moving the sensor head. Align the sensor until 0.
Installation Instructions Rotary Encoders 1 Attach your hub/scale assembly to the rotary device. Refer to the interface drawing. The reflective surface of the scale must face the sensor. 3 Be sure power is off before connecting the sensor. Connect the M1200 or M1500P to your interface electronics using the pinout diagram described on the interface drawing. Power up the system. 2 Install the sensor on your mounting surface referencing the appropriate datum surface as shown on the interface drawing.

Reference Section Installation of Linear Scales Positioning the Scale Note: Before beginning mounting procedure, use talc-free gloves or finger cots to handle the scales. "Benching" the scale to the system means aligning the scale by means of benching pins. Pin locations are described on the appropriate interface drawing. Two benching pins are recommended on the long side of the scale and one at the end as shown . This is marked datum A on the interface drawing. the benching pins in from either end.
Cleaning scales General Particle Removal Blow off the contamination with nitrogen, clean air, or a similar gas. Contamination Removal Use a lint-free cleanroom wipe or cotton swab dampened with isopropyl alcohol or acetone only to wipe the surface clean. Handle the scale by the edges. Do not scrub the scale.
